The DB7 series are DC blocks of SMA connector types, with a maximum operating frequency up to 18 GHz and the best performance specification from 30 MHz to 16 GHz, which is very suitable for 5G sub-6 GHz, WiFi-6,... etc.
When testing active components, you can use the DB7 to block the DC to avoid current flowing into the test instrument, and to protect the safety of the test instrument.
In addition, DB7 provides extremely low insertion loss and excellent return loss to improve measurement accuracy.
